Marson, they told me that almost all cataract surgery needs a laser follow-up after two or three years.
They explained, with diagrams, how the muscles behind the eye usually develops scar tissue from the original surgery, and as the tissue thickens, it moves the lens ever so slightly, which is enough to put it out of sharp focus.
The laser procedure, which takes only 30 seconds, burns away enough scar tissue to allow the lens to return to its normal focus.
(While the actual laser procedure takes just 30 seconds or so, the waiting room bit, waiting for the pupil enlargement etc to happen, is a half-hour job.)
